.To all whom t may concorre:

Be it known that I, ALFRED CHARLES AD- LER, a citizen of the United States, residing at Somerville, inthe county of Middlesex and State of Massachusetts, have4 invented a new and useful Self-InkingRotary Rubber Stamp, of which the following is a specification.

This invention relates to an improvement in rotary stamps of the self-inking class, and has for its object to provide such a stamp of simple, inexpensive, and efficient construction, in which provision is made for regulating the strength of impression for adjusting the pressure of the inking-roller and for bringing rollers of different colors into workin g relation to the printing-roller.

Other objects and advantages of the invention will appear in the course of the subjoined description.

The invention consists in certain novel features and details of con struction and arrangement of parts, whereby simplicity and increased utility are attained, as hereinafter fully described, illustrated in the drawings, and nally pointed out in the claims hereto appended. v

In the accompanyingdrawings, Figure l is a perspective view of the improved self-inking rotary stamp, the same being constructed in accordance with the present invention. Fig. 2 is a side elevation of the same. Fig. 3 is a plan view thereof. Fig. 4 is a side elevation showing the device with a group of different inking-rollers. Fig. 5 is a detail perspective view of the adjustable bearin g-frame and a triangular group of inking-rollers journaled therein. Fig. 6 is a similar view showing the construction of one of theiuking-roll- Fig. 7 is a detail view of a modified form of inking-roller.

Similar numerals of reference design ate corresponding parts in the several figures of the drawings.

Referring to the drawings, l designates a suitable handle, which receives the shank 2 of a bifurcated frame 3, having oppositelydisposed arms 4, the extremities of which have alined openin gs, in which is received the spindle 5 of the printing-roller 6 of the improved radial thickness of said treads corresponding to the proximal thickness of the rubber form and serving to equalize the pressure upon such form, so that an even impression may be obtained. The peripheral portion of the treads 7 are also transversely milled or serrated, so that a iirm frictional engagementis established at all times between the printingroller and the surface being printed.

The arms of the frame in which the printingroller is journaled are inclined downwardly from the shank of the handle toward their eX- tremities, so as to locate the center of the printing-roller below the plane of the handle. The object in thus depressing the arms of said frame is to provide for the attachment to the upper flat bearing-surface of said frame of a supplemental frame in which the inkingroller is journaled. This supplementalframe 8, like the main frame, comprises opposite spaced arms 9, which receive in their extremities the spindle l0 of the inking-roller ll. This supplemental frame is also formed with a slotted extension l2, by means of which it is secured to the main frame with the aid of a bindin g-screw 13, the shank of which enters a threaded socket in the main frame, the head bearing against the upper surface of the inking-roller frame. mitsy of adjusting the inking-roller toward or away from the printing-roller for establishing the desired contact between-the inking-roller and the rubber form; Not only this, but the inking-roller and its frame may be readily detached from the main frame and another frame with an inking-roller of different color substituted.

The inking-roller may be made in one piece or in several sections, each of which is in the form of a Washer or annular pad l/l. A sufficient number of these Washers or pads, which are made preferably of felt, are mounted upon a tubular bearing-sleeve l5 and pressed firmly together, and this bearing-sleeve re- This construction also adceives the spindle of the inking-roller frame above referred to. Shouldit be desirable Ato print in two colors at the same time-that is, to apply ink of one color to a portion of the form and ink of another color to the remaining portion thereofan inking-roller with a V-shaped groove 16 may be utilized in lieu of the solid one, the said groove serving to effectively prevent the different colors from comminglinr. The form of the roller last referred to is illustrated in Fig. 7.

In Fig. 4 and 5 I have shown how a series` or group of inking-rollers may be used in connection with the same rotary stamp. This is accomplished by journaling three, or more or less, rollers in and between an oppositely-disposed pair ofbearing-plates 17. Three of these rollers are shown, and in this event the bearing-plates 17 are made triangular in shape, the inking-rollers being journaled upon spindles passing through the angles of such plates. Each of the plates is also formed witha central-bearin g opening, by mea-ns of which the cluster or group of rollers is revolubly mounted upon the spindle 1S of the supplemental roller-frame. Intermediate the rollers `and centrally of each iiat side or edge of one of the bearing-plates 17 `is a notch 19, which is adapted to be engaged by the swinging end of alock-plate 20, pivotallymounted upon the inking-roller frame by means of abindingscrew 21.

The locking-plate 20 may be swung llaterally out of engagement with the bearingplate 17, allowing any one of the inkingrollers to be brought into contact with the impression roller, when theV locking-plate may be re-engaged with the desired notch in the bearing-plate and the adjusted position of the inking-roller thus preserved.

`It' desired, the binding-screw 21 may be tightened for preventing accidental disengagement of the locking-platej A retaining-spring 22 is secured at one end to the printing-roller frame and has. its forward free end crimped `to engage a laterallyprojecting pin or stud 23 at the side of the printingroller- The printing-roller is al-` lowed to revolve freely until the pin 23 snaps into the crimp of the retaining-spring, where` upon further motion of the printing-roller is prevented. This construction enables the operator to start the printing-roller at the` proper point, so Vas to make one complete im'- pression of the form on the periphery of saidv roller.

By means of the construction above described it will be seen that a very imple and eflieient marking device is obtained which may be manufactured in any desired size: either for marking linen or labeling or addressing packages, boxes, rbc. By the con-` struction described it is also an easy matter to change the inking-rollers, employ inkingrollers of different colors, and to adjust them into the proper workin g relation to the form. The pressure upon the form of the printingroller is also equalized by means of the rubber treads hereinbefore described.

Various changes in the'form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed as new is- 1. In a self-inking stamp, the combination of a bifurcated frame provided with a straight flat portion to form a bearing-surface and having its arms downwardly deflected, a printing-roller journaled between said arms with its center arranged in a plane beneath the plane of the' iiat bearing-surface of the frame, a straight flat supplemental frame arranged on the flat bearing-surface of the said frame in aplane above the center of theprinting-roller and provided with straight forwardly-extending arms, said supplemental frame having a longitudinal slot, a substantially vertically disposed clamping screw passing through said slot-and adj ustably connecting the frames, and an inking-roller journaled between the arms ofthe supplei'nental frame and bearing against the printing-roller, substantially as described.

2. In a rotary self-inking stamp, the combination with the printing-roller, the frame in which said roller is mounted, and the handle for actuating Vsaid frame, 01": a `longitudinally-adjustable inking-roller frame, a group of inking-rollers severally journaled in bearingplates pivotally mounted in the inking-roller frame, and means for `holding either of said inking-rollers in engagement with the printing-roller, substantially as and for the purpose described.

In a rotary self-inking stamp, the com bination with the printing-roller and the frame in which said' roller is mounted, of a longitudinally adjust-able inking roller frame, a group or series of inking-rollers severally journaled in bearing-plates which are in turn journaled in the inking-roller frame, and an adjustable locking plate adapted to be moved into and out of engagement with one of said bearing-plates, substantially as and for the purpose described.

In testimony that I claim the foregoing as my own I have hereto atxed my signature in the presence of two witnesses.

ALFRED CHARLES ADLER.
